Diabetic foot complications represent a major global health challenge, with a high prevalence among patients with diabetes. A diabetic foot ulcer (DFU) not only affects the patient›s quality of life but also increases the risk for amputation.

Worldwide, a DFU occurs every second, and an amputation occurs every 20 seconds. The limitations of current detection and intervention methods underline the urgent need for innovative solutions.

Recent advances in artificial intelligence (AI) have paved the way for individualized risk prediction models for chronic wound management. These models use deep learning algorithms to analyze clinical data and images, providing personalized treatment plans that may improve healing outcomes and reduce the risk for amputation.

AI-powered tools can also be deployed for the diagnosis of diabetic foot complications. Using image analysis and pattern recognition, AI tools are learning to accurately detect signs of DFUs and other complications, facilitating early and effective intervention. Our group and others have been working not only on imaging devices but also on thermographic tools that — with the help of AI — can create an automated “foot selfie” to predict and prevent problems before they start.

AI’s predictive capabilities are instrumental to its clinical value. By identifying patients at high risk for DFUs, healthcare providers can implement preemptive measures, significantly reducing the likelihood of severe complications.

Although the potential benefits of AI in diabetic foot care are immense, integrating these tools into clinical practice poses challenges. These include ensuring the reliability of AI predictions, addressing data privacy concerns, and training healthcare professionals on the use of AI technologies.

As in so many other areas in our lives, AI holds the promise to revolutionize diabetic foot and limb preservation, offering hope for improved patient outcomes through early detection, precise diagnosis, and personalized care. However, realizing this potential requires ongoing research, development, and collaboration across the medical and technological fields to ensure these innovative solutions can be effectively integrated into standard care practices.

It should come as no surprise that when physicians speak out on social and political issues, there is sometimes a backlash. This can range from the typical trolling that occurs online to rarer cases of professional penalties. Two doctors were fired by NYU Langone Health late last year after they posted social media messages about the Israel-Hamas war. Still, many physicians are not only willing to stand up for what they believe in, but they see it as an essential part of their profession. 
"We're now at a place where doctors need to engage in public advocacy as an urgent part of our job," wrote Rob Davidson, MD, an emergency department physician, at the onslaught of the COVID-19 pandemic. In an Op-Ed piece for The Guardian, Dr. Davidson noted how the virus forced many physicians into becoming "activist doctors," calling for adequate personal protective equipment and correcting misinformation. "What we want above all is for the administration to listen to doctors, nurses, and frontline health workers - and stop playing politics," he wrote. 

'It's Not About Being Political' 

The intersection of medicine and politics is hardly new. Doctors frequently testify before Congress, sharing their expertise on issues concerning public health. This, however, isn't the same as "playing politics." 
"I'm not taking political stances," said Megan Ranney, MD, Dean of the Yale School of Public Health. "Rather, I'm using science to inform best practices, and I'm vocal around the area where I have expertise where we could do collectively better." 
Dr. Ranney's work to end firearm injury and death garnered particular attention when she co-authored an open letter to the National Rifle Association (NRA) in 2018. She wrote the letter in response to a tweet by the organization, admonishing physicians to "stay in their lane" when it comes to gun control.  
Dr. Ranney's letter discussed gun violence as a public health crisis and urged the NRA to "be part of the solution" by joining the collective effort to reduce firearm injury and death through research, education, and advocacy. "We are not anti-gun," she stated. "We are anti-bullet hole," adding that "almost half of doctors own guns." 
The NRA disagreed. When Dr. Ranney testified before Congress during a hearing on gun violence in 2023, NRA spokesperson Billy McLaughlin condemned her testimony as an effort to "dismantle the Second Amendment," calling Dr. Ranney "a known gun control extremist." 
"If you actually read what I write, or if you actually listen to what I say, I'm not saying things on behalf of one political party or another," said Dr. Ranney. "It's not about being political. It's about recognizing our role in describing what's happening and making it clear for the world to see. Showing where, based off of data, there may be a better path to improve health and wellbeing." 
In spite of the backlash, Dr. Ranney has no regrets about being an activist. "In the current media landscape, folks love to slap labels on people that may or may not be accurate. To me, what matters isn't where I land with a particular politician or political party, but how the work that I do improves health for populations." 

When the Need to Act Outweighs the Fear 

Laura Andreson, DO, an ob.gyn, took activism a step further when she joined a group of women in Tennessee to file a suit against the state, the attorney general, and the state board of medical examiners. The issue was the Tennessee's abortion ban, which the suit claimed prevented women from getting "necessary and potentially life-saving medical care."  
Dr. Andreson, who says she was "not at all" politically active in the past, began to realize how the abortion ban could drastically affect her profession and her patients. "I don't know what flipped in me, but I just felt like I could do this," she said. 
Like Dr. Ranney, Dr. Andreson has been as visible as she has been vocal, giving press conferences and interviews, but she acknowledges she has some fears about safety. In fact, after filing the lawsuit, the Center for Reproductive Rights recommended that she go to a website, DeleteMe, that removes personal data from the internet, making it more difficult for people to find her information. "But my need to do this and my desire to do this is stronger than my fears," she added. 
Dr. Andreson, who is part of a small practice, did check with both her coworkers and the hospital administration before moving forward with the lawsuit. She was relieved to find that she had the support of her practice and that there wasn't anything in the hospital bylaws to prevent her from filing the lawsuit. "But the people in the bigger institutions who probably have an even better expert base than I do, they are handcuffed," she said. 
It has been, in Dr. Andreson's words, "a little uncomfortable" being on the board of the Tennessee Medical Association when the Tennessee Board of Medical Examiners is part of the lawsuit. "We're all members of the same group," she said. "But I'm not suing them as individuals; I'm suing them as an entity that is under our government." 
Dr. Andreson said most people have been supportive of her activist work, though she admitted to feeling frustrated when she encounters apathy from fellow ob.gyns. She got little response when she circulated information explaining the abortion laws and trying to get others involved. But she still sees education as being a key part of making change happen.  
"I think advocacy, as someone who is considered a responsible, trustworthy person by your community, is important, because you can sway some people just by educating them," she said. 

Fighting Inequities in Medicine and Beyond 

Christina Chen, MD, says she felt very supported by her medical community at the Mayo Clinic in Rochester, Minnesota, when she and 16 other Asian American physicians posted a video on Instagram in 2020 highlighting increased violence and harassment of Asian Americans during COVID-19. It soon went viral, and the Mayo Clinic distributed it across their social media channels. The only negative repercussions Mayo faced were a few posts on social media saying that politics should not be brought into the healthcare space. Dr. Chen disagrees. 
"Social issues and political decisions have direct impact on the health of our communities," Dr. Chen said. "We know that we still have a long way to go to solve health inequities, which is a public health problem, and we all play a huge role in voicing our concerns." 
Activism, however, seems to be more complicated when it involves physicians being critical of inequities within the medical field. Nephrologist, Vanessa Grubbs, MD, MPH, founded the nonprofit Black Doc Village in 2022 to raise awareness about the wrongful dismissal of Black residents and expand the Black physician workforce. 
Dr. Grubbs said that the medical community has not been supportive of her activism. "The reason why I'm no longer in academia is in part because they got very upset with me tweeting about how some trainees are biased in their treatment of attendings," she said. "Senior White men attendings are often treated very differently than junior women of color faculty." 
Dr. Grubbs also expressed her views in 2020 essay in the New England Journal of Medicine where she criticized academic medical institutions for ignoring systemic racism, paying lip service to diversity, equity, and inclusion, and staying "deafeningly silent" when issues of racism are raised. 
Today, Black Doc Village is focused on conducting research that can be used to change policy. And Dr. Grubbs now has the full support of her colleagues at West Oakland Health, in Oakland, California, which aspires to advance the Bay Area Black community's health and dignity. "So, no one here has a problem with me speaking out," she added. 
The emphasis on data-driven activism as opposed to "playing politics," is a recurring theme for many physicians who publicly engage with social issues. 
"It's not partisan," Dr. Ranney said. "Rather, it's a commitment to translating science into actionable steps that can be used regardless of what political party you are in. My job is not to be on one side or the other, but to advance human health." These doctors challenge their critics to explain how such a goal is outside their purview.

ATLANTA — Patients with acute coronary syndrome (ACS) who had a myocardial infarction or unstable angina and underwent percutaneous coronary intervention (PCI) had a 76% lower rate of hospital readmission after 6 months if they participated in a remote monitoring protocol compared with similar patients who had standard post-discharge care, results of a new trial suggest.

The TELE-ACS trial showed that at 6 months, telemedicine patients also had statistically significantly lower rates of post-discharge emergency department visits, unplanned coronary revascularizations, and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness. However, the rates of major adverse cardiovascular events (MACE) were similar between the two groups. The protocol included consultation with a cardiologist who reviewed home-monitoring data.

“The team was able to aid in preventing unnecessary presentations and advised the patients to seek emergency care whenever was necessary,” Nasser Alshahrani, MSc, a clinical research fellow at Imperial College London, said while presenting the results at the American College of Cardiology meeting. “The TELE-ACS protocol provided a significant reduction in readmission rates post-ACS and other adverse events.” 

The study findings were published online simultaneously in the Journal of the American College of Cardiology.
 

Telemedicine Protocol

The trial, conducted from January 2022 to April 2023, randomly assigned 337 patients to telemedicine or standard care when they were discharged after PCI and had at least one cardiovascular risk factor. The telemedicine protocol consisted of 12-lead electrocardiogram belt, an automated blood-pressure monitor, and a pulse oximeter. 

Patients in the telemedicine arm initiated the remote monitoring protocol if they thought they had cardiac symptoms. The majority (86%) were men with what the study described as “a high preponderance of cardiovascular risk factors.” Average age was 58.1 years. 

If a telemedicine patient initiated the protocol, a cardiologist remotely assessed the patient’s symptoms and channeled the patient to the appropriate care pathway, whether reassuring the patient or sending them to a primary care physician or emergency department, or to call emergency services. Patients who didn’t get a call back from the cardiologist within 15 minutes were told to seek care in the standard clinical pathway.

Telemedicine patients were given the telemonitoring package and training in how to use the devices before they were discharged. They also received three follow-up quality control calls in the first two months to ensure they were using the equipment correctly. They kept the telemonitoring equipment for 8 months, but were followed out to 9 months. Six telemedicine patients dropped out while one standard care patient withdrew from the study.

Results showed that at 6 months, telemedicine patients had statistically significantly lower rates of post-discharge emergency department visits (25% vs 37%, P < .001), unplanned coronary revascularizations (3% vs 9%, P < .01) and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness (a 13% to 18% difference for each symptom, P < .01).

MACE rates were similar between the two groups.

At 9 months, 3 months after the protocol ended, 20 telemedicine patients and 50 standard-care patients were readmitted to the hospital, while 52 and 73, respectively, went to the emergency department.

The telemedicine patients also had shorter hospital stays: an average of 0.5 and 1.2 days at 6 and 9 months, respectively, vs 1.5 and 1.8 days in the standard treatment arm (P < .001 for both).

Mr. Alshahrani noted several limitations with the study, namely that 86% of participants were men, and that the intervention was only offered to people who had smartphones. “The high level of support for the telemedicine group, with prompt cardiology responses, may be challenging to replicate outside a trial setting, requiring significant investment and training,” he added.
 

Human Element Key

In an interview from London after the presentation, lead author Ramzi Khamis, MB ChB, PhD, said, “This was quite a basic study. Really what we did was we integrated a clinical decision-making algorithm that we perfected with some quite novel but basic technology.” Future research should strive to add a home troponin test to the protocol and an artificial intelligence component, he said.

However, Dr. Khamis noted that human interaction was key to the success of the TELE-ACS trial. “The human factor is very important here and I think it would be really interesting to have a head-to-head comparison of human interaction with remote monitoring vs an AI-driven interaction,” he said. “I have my doubts that AI would be able to beat the human factor here.”

Lawrence Phillips, MD, medical director of outpatient cardiology at NYU Langone Heart, told this news organization that the study was appropriately powered to evaluate the telemedicine protocol, and that it could serve as a template for other studies of remote monitoring in cardiology. 

“I think that this study is forming the foundation of evolving telemedicine data,” he said. “It shows really interesting results, and I’m sure it’s going to be reproduced in different ways going forward.”

While other studies have shown the utility of telemedicine to decrease unnecessary hospitalizations, this study went one step further, Dr. Phillips said. “What was unique about this study was the package that they put together,” he added. “It was a combination of telehealth and being able to speak with someone when you have concerns with objective data of an electrocardiogram, blood-pressure cuff, and oxygen level assessment, which is an interesting approach having that ejective data with [a] subjective element.”

ATLANTA — Patients with acute coronary syndrome (ACS) who had a myocardial infarction or unstable angina and underwent percutaneous coronary intervention (PCI) had a 76% lower rate of hospital readmission after 6 months if they participated in a remote monitoring protocol compared with similar patients who had standard post-discharge care, results of a new trial suggest.

The TELE-ACS trial showed that at 6 months, telemedicine patients also had statistically significantly lower rates of post-discharge emergency department visits, unplanned coronary revascularizations, and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness. However, the rates of major adverse cardiovascular events (MACE) were similar between the two groups. The protocol included consultation with a cardiologist who reviewed home-monitoring data.

“The team was able to aid in preventing unnecessary presentations and advised the patients to seek emergency care whenever was necessary,” Nasser Alshahrani, MSc, a clinical research fellow at Imperial College London, said while presenting the results at the American College of Cardiology meeting. “The TELE-ACS protocol provided a significant reduction in readmission rates post-ACS and other adverse events.” 

The study findings were published online simultaneously in the Journal of the American College of Cardiology.
 

Telemedicine Protocol

The trial, conducted from January 2022 to April 2023, randomly assigned 337 patients to telemedicine or standard care when they were discharged after PCI and had at least one cardiovascular risk factor. The telemedicine protocol consisted of 12-lead electrocardiogram belt, an automated blood-pressure monitor, and a pulse oximeter. 

Patients in the telemedicine arm initiated the remote monitoring protocol if they thought they had cardiac symptoms. The majority (86%) were men with what the study described as “a high preponderance of cardiovascular risk factors.” Average age was 58.1 years. 

If a telemedicine patient initiated the protocol, a cardiologist remotely assessed the patient’s symptoms and channeled the patient to the appropriate care pathway, whether reassuring the patient or sending them to a primary care physician or emergency department, or to call emergency services. Patients who didn’t get a call back from the cardiologist within 15 minutes were told to seek care in the standard clinical pathway.

Telemedicine patients were given the telemonitoring package and training in how to use the devices before they were discharged. They also received three follow-up quality control calls in the first two months to ensure they were using the equipment correctly. They kept the telemonitoring equipment for 8 months, but were followed out to 9 months. Six telemedicine patients dropped out while one standard care patient withdrew from the study.

Results showed that at 6 months, telemedicine patients had statistically significantly lower rates of post-discharge emergency department visits (25% vs 37%, P < .001), unplanned coronary revascularizations (3% vs 9%, P < .01) and cardiovascular symptoms, such as chest pain, shortness of breath and dizziness (a 13% to 18% difference for each symptom, P < .01).

MACE rates were similar between the two groups.

At 9 months, 3 months after the protocol ended, 20 telemedicine patients and 50 standard-care patients were readmitted to the hospital, while 52 and 73, respectively, went to the emergency department.

The telemedicine patients also had shorter hospital stays: an average of 0.5 and 1.2 days at 6 and 9 months, respectively, vs 1.5 and 1.8 days in the standard treatment arm (P < .001 for both).

Mr. Alshahrani noted several limitations with the study, namely that 86% of participants were men, and that the intervention was only offered to people who had smartphones. “The high level of support for the telemedicine group, with prompt cardiology responses, may be challenging to replicate outside a trial setting, requiring significant investment and training,” he added.

SAN DIEGO — Using ImPrint, an immune-related biomarker, clinicians can identify patients with breast cancer who are likely to respond to neoadjuvant immunotherapy, according to data from the ongoing phase 2 I-SPY2 trial.

Patient selection based on ImPrint class can result in high response rates and spare nonresponders the toxicities of immunotherapy, said Denise M. Wolf, PhD, during her presentation of the study results at the annual meeting of the American Association for Cancer Research (AACR).

“Our results show that patients with ER+/HER2-/ImPrint+ breast cancer have a very high probability of achieving complete response to immunotherapy, whereas those who are ER+/HER2-/ImPrint- have a low probability of responding,” noted Dr. Wolf, PhD, MSc of the University of California, San Francisco (UCSF), in an interview.

She added that, although effective, immunotherapy also carries the risk of serious immune-related toxicities, and knowledge of ImPrint class can help patients and physicians determine whether immunotherapy is a good treatment option. “Many patients will be willing to take the risk of immunotherapy toxicities if their odds of responding are very high, as is the case for ImPrint+ patients, but [are] likely less enthused with a low likelihood of response,” Dr. Wolf said during the interview.
 

Need for Predictive Biomarkers for Neoadjuvant Immunotherapy

Although neoadjuvant immunotherapy has become the standard treatment for patients with early-stage triple-negative breast cancer (TNBC), chemotherapy remains the mainstay of treatment for patients with hormone receptor–positive (HR+), human epidermal growth factor receptor 2–negative (HER2-) breast cancer. The I-SPY2 clinical trial is the first randomized clinical study to assess the efficacy of immunotherapy in the high-risk population of patients with HR+/HER2-, Dr. Wolf said. Data from this study suggest that a subset of HR+/HER2- patients may also derive substantial benefit from this approach compared with standard chemotherapy.

“We and others have previously observed that a minority of ER+/HER2- breast cancers are enriched for tumor-infiltrating lymphocytes and that high levels of immune-related gene signatures associate with improved survival in this subtype, as well as in TNBC,” noted Dr. Wolf during an interview.

She explained that patients with high-risk ER+/HER2- breast cancer were not responding to any of the experimental agent classes tested in the trial and showed particularly poor outcomes, and that she and her colleagues “wanted to see if immune-oncology agents would impact response in these patients.”
 

ImPrint, an Immune Expression Signature

Preliminary data from the I-SPY2 trial showed that immune-related gene signatures were associated with pathologic complete response (pCR) in patients with HR+/HER2- breast cancer treated with immunotherapy. This observation allowed investigators to develop a clinically applicable immune classifier, termed ImPrint, to predict response to immunotherapy in this population.

This immune classifier is a 53-gene signature developed using data from the first anti–programmed death-1 (PD-1) arm that included patients treated with pembrolizumab, explained Dr. Wolf.
 

Performance of ImPrint in Patients With HR+/HER2- Breast Cancer

Dr. Wolf presented new data on the performance of ImPrint in 204 patients with high-risk HR+/HER2- breast cancer from the following five immunotherapy arms of the I-SPY2 trial, at the meeting. These arms included: anti–PD-1, anti–PDL-1 plus PARP inhibitor, anti–PD-1/TLR9 dual immunotherapy, and anti–PD-1 with or without LAG3 inhibitor. Data from 191 patients treated with the current standard of care (paclitaxel followed by adriamycin and cyclophosphamide cytoxan) were included in the analysis as a control.

The pCR in the entire population across these five immunotherapy arms was 33%. The response rate in the control arm was 13.5%.

“The high pCR in the immunotherapy groups is remarkable given the traditionally poor response of HR+/HER2- tumors to standard neoadjuvant chemotherapy,” said Ritu Aneja, PhD, the associate dean for research and innovation at the University of Alabama at Birmingham and a breast cancer expert, who was not involved in the I-SPY2 trial.

When patients were stratified according to ImPrint status, significant differences were observed among the groups. In this analysis, 28% of HR+/HER2- patients were classified as ImPrint positive (likely sensitive) based on ImPrint expression levels in pretreatment mRNA samples, and these individuals achieved pCR rates as high as 76% with immunotherapy.

In comparison, pCR rates were only 16% in ImPrint-negative (likely resistant) patients. The highest response rate was observed in the anti–PD-1/TLR9 dual immunotherapy arm, with a pCR rate of greater than 90% in ImPrint-positive patients. In the control arm, pCR rates were 33% in ImPrint-positive and 8% in ImPrint-negative patients.

“These results suggest that a subset of [patients with] high-risk HR+/HER2- breast cancers is highly sensitive to immunotherapy,” said Dr. Aneja in an interview. “By using a specific and sensitive selection strategy like ImPrint, we may be able to identify patients who can achieve pCR rates similar to what we see with the best neoadjuvant therapies in triple-negative and HER2-positive disease.”
 

Ability of ImPrint to Predict Long-Term Outcomes

During her talk, Dr. Wolf explained that she and her research team currently do not have sufficient follow-up data to assess the ability of ImPrint to predict long-term outcomes. Therefore, they used the pCR data to predict long-term disease-free survival (DRFS) outcomes. Based on their model, HR+/HER2-/ImPrint+ patients treated with immunotherapy were estimated to have a 91% 5-year DRFS rate, compared with 80% for those receiving standard chemotherapy alone. This represents a 52% reduction in the risk of disease recurrence.

“This suggests not only a higher immediate response rate to therapy but also potential long-term benefits for patients identified as ImPrint+,” Dr. Aneja said, commenting on the significance of the DRFS data, during the interview, She added that the ability to predict longer-term outcomes is a critical advantage in selecting the most effective treatment strategies for patients.
 

Comparison of ImPrint With Other Biomarkers

The investigators compared ImPrint to other potential biomarkers for immunotherapy response, including MammaPrint (ultra) High2 risk (MP2) and tumor grade. During her talk, Dr. Wolf showed data demonstrating that ImPrint is a more precise predictor of pCR, with higher response rates than either of those other markers.

The pCR rates for MP2 and grade III were 56% and 45%, respectively, which are much smaller than the pCR rates observed for ImPrint+ patients (75%).

“This difference underscores ImPrint’s effectiveness in distinguishing patients who could benefit from immunotherapy, offering a pCR prediction accuracy that is significantly higher than seen with other biomarkers that have been proposed as selection markers for neoadjuvant immunotherapy trials in HR+/HER2- breast cancers, such as MP2 and tumor grade,” said Dr. Aneja, during the interview.
 

Looking Ahead — Implementation of Imprint for Patient Selection

Dr. Aneja echoed that the findings from the I-SPY2 trial advocate for the integration of biomarker-driven approaches, particularly the use of the ImPrint classifier, into the treatment planning process for high-risk HR+/HER2- breast cancer.

“This approach can enable clinicians to identify patients who are more likely to benefit from immunotherapy, thus personalizing treatment strategies and potentially enhancing treatment efficacy while minimizing exposure to unnecessary toxicity for those unlikely to respond,” she said.

Dr. Aneja added that while the I-SPY2 trial offers promising data on ImPrint’s efficacy, additional prospective studies are needed to validate these findings across diverse patient populations and settings, as well as the correlation between biomarker positivity and long-term clinical outcomes, including DRFS and overall survival. “This will help to better understand the full spectrum of benefits provided by immunotherapies in biomarker-selected patient groups,” she said.

Dr. Wolf and Dr. Aneja reported no relationships with entities whose primary business is producing, marketing, selling, reselling, or distributing healthcare products used by or on patients.

“This suggests not only a higher immediate response rate to therapy but also potential long-term benefits for patients identified as ImPrint+,” Dr. Aneja said, commenting on the significance of the DRFS data, during the interview, She added that the ability to predict longer-term outcomes is a critical advantage in selecting the most effective treatment strategies for patients.
 

Comparison of ImPrint With Other Biomarkers

The investigators compared ImPrint to other potential biomarkers for immunotherapy response, including MammaPrint (ultra) High2 risk (MP2) and tumor grade. During her talk, Dr. Wolf showed data demonstrating that ImPrint is a more precise predictor of pCR, with higher response rates than either of those other markers.

The pCR rates for MP2 and grade III were 56% and 45%, respectively, which are much smaller than the pCR rates observed for ImPrint+ patients (75%).

“This difference underscores ImPrint’s effectiveness in distinguishing patients who could benefit from immunotherapy, offering a pCR prediction accuracy that is significantly higher than seen with other biomarkers that have been proposed as selection markers for neoadjuvant immunotherapy trials in HR+/HER2- breast cancers, such as MP2 and tumor grade,” said Dr. Aneja, during the interview.
 

Looking Ahead — Implementation of Imprint for Patient Selection

Dr. Aneja echoed that the findings from the I-SPY2 trial advocate for the integration of biomarker-driven approaches, particularly the use of the ImPrint classifier, into the treatment planning process for high-risk HR+/HER2- breast cancer.

“This approach can enable clinicians to identify patients who are more likely to benefit from immunotherapy, thus personalizing treatment strategies and potentially enhancing treatment efficacy while minimizing exposure to unnecessary toxicity for those unlikely to respond,” she said.

Dr. Aneja added that while the I-SPY2 trial offers promising data on ImPrint’s efficacy, additional prospective studies are needed to validate these findings across diverse patient populations and settings, as well as the correlation between biomarker positivity and long-term clinical outcomes, including DRFS and overall survival. “This will help to better understand the full spectrum of benefits provided by immunotherapies in biomarker-selected patient groups,” she said.

Dr. Wolf and Dr. Aneja reported no relationships with entities whose primary business is producing, marketing, selling, reselling, or distributing healthcare products used by or on patients.

Power-washing is no longer just for blasting grimy driveways and stripping flaky paint. It’s good for work inside the gut, too.

In a proof-of-concept study, a “novel systematically directed high-pressure liquid spray,” delivered via the ERBEJET flexible probe, showed promise for collecting cytology specimens from the stomachs of patients undergoing endoscopy for gastric cancer screening or surveillance, reported lead author Charles J. Lightdale, MD, of Columbia University Irving Medical Center, New York City, and colleagues.

“Systematic random biopsies (updated Sydney protocol) have been recommended to increase detection of gastric intestinal metaplasia (GIM) and dysplasia,” the investigators wrote in Techniques and Innovations in Gastrointestinal Endoscopy. “However, random biopsies can be laborious, time consuming, costly, and susceptible to sampling error owing to the large surface area of the stomach.”

Power-washing, in contrast, with the pressure dial turned to 10 bar, involves spraying the gut in a systematic fashion “using sweeping and painting motions” to dislodge cells from the mucosa. These specimens are then suctioned from the resultant pools of liquid, mixed 1:1 with 10% formalin, and shipped to the lab.
 

Boom! Cytology!

Just to be sure, however, the nine patients involved in the study also underwent standard-of-care biopsy collection from areas of interest, followed by random sampling according to the updated Sydney protocol. Two of the patients were power-washed again 12 months later for endoscopic surveillance.

Power-washing added 7-10 minutes to standard endoscopy time and generated 60-100 mL of liquid for collection. Post suction, a closer look at the gastric mucosa revealed “scattered superficial erosions,” while blood loss was deemed “minimal.” The procedure appeared well tolerated, with no aspiration or esophageal reflux during endoscopy, or adverse events reported by patients after 1 week of follow-up.

Cytopathology samples were deemed satisfactory and yielded “multiple strips and large clusters of cells.” These were sufficient to diagnose GIM in three patients and reactive glandular changes with inflammation in one patient, with findings confirmed on biopsy. In contrast, the power-washed cells from one patient were “highly suspicious” for dysplasia, but biopsies were negative.

Although the study was too small for a reliable comparison with the Sydney protocol, Dr. Lightdale and colleagues concluded that the power-wash approach deserves further investigation.

“Use of power-wash to obtain cytology has the potential to improve endoscopic screening and surveillance protocols for detecting GIM and dysplasia and to reduce morbidity and mortality from gastric cancer,” they wrote.

The investigators predicted that power-washing is likely safe in most patients, although it may be unsuitable for those with noncorrectable coagulopathies or in patients who cannot stop anticoagulants. Postsurgical patients, on the other hand, should tolerate the procedure just fine.

Patients with risk of gastric cancer “might be an important group” for evaluating the power-wash procedure, the investigators wrote, noting that combining the approach with artificial intelligence could one day yield even better results.

In the meantime, Dr. Lightdale and colleagues — like so many weekend warriors wielding a power-washer — are going to see if a different nozzle will take their work to the next level.

“We are actively studying a catheter with a broader stream and the potential to increase efficiency and decrease procedure time,” they wrote. “Another catheter design might allow for simultaneous spray and suction, so that cytology samples from specific regions of the stomach could be separately analyzed.”

This study was funded by Dalio Philanthropies, the Price Family Foundation, and the Frederic and Patricia Salerno Foundation. The investigators disclosed relationships with Boston Scientific, Interscope, Medtronic, and others.

The Diagnosis: Hypertrophic Lichen Planus

Two biopsies from the left lateral foot revealed hyperkeratosis, wedge-shaped hypergranulosis, irregular acanthosis, and a bandlike lymphocytic infiltrate in the superficial dermis with a classic sawtooth pattern of the rete ridges (Figure 1). Based on the clinical findings and histopathology, the patient was diagnosed with hypertrophic lichen planus (LP) and was treated with clobetasol ointment 0.05%, which resulted in progression of the symptoms. She experienced notable improvement 3 months after adding methotrexate 12.5 mg weekly (Figure 2).

Lichen planus is an idiopathic chronic inflammatory condition of the skin and mucous membranes that classically manifests as pruritic violaceous papules and plaques, which commonly are found on the wrists, lower back, and ankles.¹ The most common variants of LP are hypertrophic, linear, mucosal, actinic, follicular, pigmented, annular, atrophic, and guttate.² The clinical presentation and biopsy results in our patient were consistent with the hypertrophic variant of LP, which is a chronic condition that most often manifests on the lower legs, especially around the ankles, as hyperkeratotic papules, plaques, and nodules.^2,3 The exact pathophysiology of hypertrophic LP is unknown, but there is evidence that the immune system plays a role in its development and that the Koebner phenomenon may contribute to its exacerbation.⁴ There is a well-known association between LP and hepatitis. Patients with chronic LP may develop squamous cell carcinoma.⁴ The variants of LP can overlap and do not exist independent of one another. Recognizing the overlap in these variants allows for earlier diagnosis and therapeutic intervention of the disease process to limit disease progression and patient clinic visits and to improve patient quality of life.

The differential diagnosis for hyperkeratotic plaques of the feet and ankles can be broad and may include keratosis lichenoides chronica, palmoplantar keratoderma, palmoplantar psoriasis, or lichen amyloidosis. These conditions are classified based on various criteria that include extent of disease manifestations, morphology of palmoplantar skin involvement, inheritance patterns, and molecular pathogenesis.⁵ Keratosis lichenoides chronica is a rare dermatosis that presents as a distinctive seborrheic dermatitis–like facial eruption. The facial eruption is accompanied by violaceous papular and nodular lesions that appear on the extremities and trunk, typically arranged in a linear or reticular pattern.⁶ Palmoplantar keratoderma represents a group of acquired and hereditary conditions that are characterized by excessive thickening of the palms and soles.⁵ Palmoplantar psoriasis is a variant of psoriasis that affects the palms and soles and can manifest as hyperkeratosis, pustular, or mixed morphology.⁷ Lichen amyloidosis is a subtype of primary localized cutaneous amyloidosis that manifests as multiple pruritic, firm, hyperpigmented, hyperkeratotic papules on the shins that later coalesce in a rippled pattern.^8,9

The first-line treatment for hypertrophic LP is topical corticosteroids. Alternative therapies include mycophenolate mofetil, acitretin, and intralesional corticosteroid injections.⁴ Treatment is similar for all of the LP variants.

The prevalence of dementia among homeless people is almost twice as high as that in housed populations in Ontario, Canada, according to the results of a new study.

The findings suggested that dementia occurs earlier in homeless individuals, and that these patients could benefit from proactive screening and housing interventions.

“Whether dementia caused the homelessness or homelessness caused the dementia, it’s a bidirectional relationship,” said lead author Richard G. Booth, PhD, RN, adjunct scientist at ICES (formerly Institute for Clinical Evaluative Sciences) and associate professor of nursing at Western University in London, Ontario, Canada.

The study was published in the April issue of The Lancet Public Health.

 

Dementia at Early Ages

The investigators used health administrative data from Ontario to compare the prevalence of dementia among homeless people with that among housed individuals in the general population and those living in low-income neighborhoods.

They included individuals aged 45 years or older on January 1, 2019, who visited hospital-based ambulatory care (such as emergency departments), were hospitalized, or visited a community health center in 2019. The researchers identified people as experiencing homelessness if they had one or more healthcare records with an indication of homelessness or unstable housing. The prevalence of dementia was ascertained as of December 31, 2019.

Included in the population-based, cross-sectional comparative analysis were 12,863 homeless people, 475,544 people in the low-income group, and 2,273,068 people in the general population group.

Dementia prevalence was 68.7 per 1000 individuals among the homeless population, 62.6 per 1000 in the low-income group, and 51.0 per 1000 in the general population group.

After adjustments for age, sex, geographical location of residence (urban vs rural), and health conditions associated with dementia, the prevalence ratio of dementia among homeless people was 1.71, compared with the low-income group, and 1.90, compared with the general population group.

Dementia also was detected in the 45- to 55-year age group among homeless people. This age is much earlier than the age at which doctors start screening their patients for cognitive decline (65 years).

“The study was not designed to define the causality but consider: If you have early-stage dementia and you are not intact enough to do basic functions of life, the likelihood of you becoming homeless is definitely increased, and vice versa. If you are homeless and suffer significant environmental and physical traumas just living on the street, you age much quicker, and you will experience geriatric symptoms such as dementia earlier in your life trajectory,” said Dr. Booth.

“The main takeaway here is that if you don’t have housing, bad things are going to happen in life.”
 

Public Health Problem

In an accompanying editorial, William J. Panenka, MD, associate professor of psychiatry at the University of British Columbia in Vancouver, British Columbia, Canada, and colleagues cited modifiable risk factors for dementia, including lower education, traumatic brain injury, substance use, smoking, mood disorders, and social isolation, many of which are disproportionately prevalent among homeless individuals.

“Ultimately, dementia could contribute to the cycle of homelessness, whereby housing instability increases the risk for brain impairment, and brain impairment makes breaking the cycle of homelessness progressively more challenging,” they wrote.

Dr. Panenka and colleagues also pointed out that the average age of homeless people is increasing. In the United States, it is now approximately 50 years. This fact underscores “the immediacy and gravity of the public health problem. A multifaceted approach that integrates healthcare, housing, and social services is needed to better understand and alleviate the health consequences of homelessness. A concerted effort at all levels is vital to inform future public health efforts and stem the tide of increasing morbidity, compromised function, and early mortality in homelessness,” they concluded.

Stephen Hwang, MD, director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital and Unity Health in Toronto, said that the study may underestimate the magnitude of the problem of dementia among homeless people.

“The methods used in this research study are very strong because they draw upon data for everyone living in the entire province of Ontario, and this is a very powerful way of looking at this challenging problem. The study probably underestimates the magnitude of the problem because to be diagnosed with dementia, patients have to have contact with healthcare providers that make that diagnosis. Often, people experiencing homelessness don’t have extensive contact with the healthcare system, and so their condition may go undiagnosed,” said Dr. Hwang.

A specialist in internal medicine, Dr. Hwang has provided healthcare for homeless people, and his research focuses on homelessness, housing, and health. He said that the findings from the Canadian study are applicable to the United States.

Forced clearances of homeless people and placing them in encampments, something that has been discussed in Florida, is unlikely to solve the problem, he said.

“The approach that has been shown to be beneficial is to engage with people and offer them housing and services that will allow them to exit homelessness without criminalizing the fact that they’re homeless. There really is no reason to think that this approach of forced clearances is going to help anyone.”

This study was supported by ICES (formerly the Institute for Clinical Evaluative Sciences), which is funded by the Ontario Ministry of Health and Ontario Ministry of Long-Term Care. Dr. Booth and Dr. Hwang reported no relevant financial relationships. Dr. Panenka reported receiving a research grant from the Canadian Institutes of Health Research.

“The main takeaway here is that if you don’t have housing, bad things are going to happen in life.”
 

Public Health Problem

In an accompanying editorial, William J. Panenka, MD, associate professor of psychiatry at the University of British Columbia in Vancouver, British Columbia, Canada, and colleagues cited modifiable risk factors for dementia, including lower education, traumatic brain injury, substance use, smoking, mood disorders, and social isolation, many of which are disproportionately prevalent among homeless individuals.

“Ultimately, dementia could contribute to the cycle of homelessness, whereby housing instability increases the risk for brain impairment, and brain impairment makes breaking the cycle of homelessness progressively more challenging,” they wrote.

Dr. Panenka and colleagues also pointed out that the average age of homeless people is increasing. In the United States, it is now approximately 50 years. This fact underscores “the immediacy and gravity of the public health problem. A multifaceted approach that integrates healthcare, housing, and social services is needed to better understand and alleviate the health consequences of homelessness. A concerted effort at all levels is vital to inform future public health efforts and stem the tide of increasing morbidity, compromised function, and early mortality in homelessness,” they concluded.

Stephen Hwang, MD, director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital and Unity Health in Toronto, said that the study may underestimate the magnitude of the problem of dementia among homeless people.

“The methods used in this research study are very strong because they draw upon data for everyone living in the entire province of Ontario, and this is a very powerful way of looking at this challenging problem. The study probably underestimates the magnitude of the problem because to be diagnosed with dementia, patients have to have contact with healthcare providers that make that diagnosis. Often, people experiencing homelessness don’t have extensive contact with the healthcare system, and so their condition may go undiagnosed,” said Dr. Hwang.

A specialist in internal medicine, Dr. Hwang has provided healthcare for homeless people, and his research focuses on homelessness, housing, and health. He said that the findings from the Canadian study are applicable to the United States.

Forced clearances of homeless people and placing them in encampments, something that has been discussed in Florida, is unlikely to solve the problem, he said.

“The approach that has been shown to be beneficial is to engage with people and offer them housing and services that will allow them to exit homelessness without criminalizing the fact that they’re homeless. There really is no reason to think that this approach of forced clearances is going to help anyone.”

This study was supported by ICES (formerly the Institute for Clinical Evaluative Sciences), which is funded by the Ontario Ministry of Health and Ontario Ministry of Long-Term Care. Dr. Booth and Dr. Hwang reported no relevant financial relationships. Dr. Panenka reported receiving a research grant from the Canadian Institutes of Health Research.

SAN DIEGO — While the concept of zoom dysmorphia is well accepted in today’s clinical practice, diagnostic criteria are lacking, especially in virtual settings, according to George Kroumpouzos, MD, PhD, who, with colleagues, recently proposed a screening tool to help identify patients with zoom dysmorphia.

The term, coined in 2020 by dermatologist Shadi Kourosh, MD, MPH, and colleagues at Harvard Medical School, Boston, refers to an altered or skewed negative perception of one’s body image that results from spending extended amounts of time on video calls. Speaking at the annual meeting of the American Academy of Dermatology, Dr. Kroumpouzos, clinical associate professor of dermatology at Brown University, Providence Rhode Island, explained that most people believe that zoom dysmorphia falls within the spectrum of body dysmorphic disorder (BDD). He described zoom dysmorphia as “a facial dysmorphia triggered or aggravated by frequent virtual meetings. Frequent use of videoconferencing platforms is linked to a distorted perception of facial images, which leads to dysmorphic concerns.”

Dr. Kroumpouzos

Individuals with zoom dysmorphia tend to scrutinize their facial features and fixate on what they think needs to improve, he continued. They experience anxiety about attending video conferences with the camera on and feel pressured to appear perfect before virtual meetings. “They find facial flaws during virtual meetings, and they believe others notice their perceived flaws,” he said. “This all has drastic effects on body dissatisfaction and self-esteem, which leads to a desire to seek cosmetic procedures. It interferes with an individual’s life and can trigger or aggravate body dysmorphic disorder.”

While several tools have been validated in cosmetic settings to screen for BDD, such as the 9-item Body Dysmorphic Disorder Questionnaire–Dermatology questionnaire, the 7-item Body Dysmorphic Disorder Questionnaire–Aesthetic Surgery questionnaire, the Cosmetic Procedure Screening Questionnaire, and the Body Dysmorphic Disorder Symptom Scale, no formal screening tools exist to identify zoom dysmorphia. To complicate matters, “identifying dysmorphic concerns in virtual settings can be challenging,” Dr. Kroumpouzos added. “This makes the recognition of zoom dysmorphia during telehealth visits even more difficult.”

Individuals who may have zoom dysmorphia may fear being misunderstood, judged, or ridiculed because of a perceived flaw in appearance, he said, making establishing rapport and eye contact difficult. “There’s a reticence and silence due to the individual’s avoidant characteristics,” he said. “Patients may become easily distracted or disengaged during telehealth visits in case of technical issues. Psychiatric comorbidities can mask symptoms related to dysmorphic concerns.”

To bridge this gap, Dr. Kroumpouzos and colleagues have proposed a screening tool, a questionnaire related to features of zoom dysmorphia, to facilitate recognition of zoom dysmorphia in virtual settings.

The first component consists of open-ended questions such as “Are you comfortable with being interviewed in a virtual appointment?” and “How do you feel about your appearance during virtual meetings?” Such questions “aim to start the dialogue, to facilitate the discussion with a patient who may be shy or avoidant,” Dr. Kroumpouzos explained.

The second component of the tool consists of questions more specific to screening for zoom dysmorphia, starting with “Are you concerned about facial flaws?” If the patient answers no, they don’t qualify for any others, he said. “But, if they answer yes to that question and yes to at least one more [question], they may have zoom dysmorphia.”

Other questions include, “Do you think that your face is not friendly to the camera?” “Do you hesitate to open the camera?” “Have you tried to hide or camouflage your flaw with your hands, hair, makeup, or clothing?” “Have you sought advice from others to improve your appearance or image?” “Do you often use the filter features of the video conferencing platform?” “Did you consider buying a new camera or equipment that helps improve your image?”

If the clinician deems the patient a candidate for the diagnosis of zoom dysmorphia, the tool recommends asking a BDD-focused question: “In the past month, have you been very concerned that there is something wrong with your physical appearance or the way one or more parts of your body look?” If the patient answers yes, “that individual should be invited to fill out a questionnaire specifically for BDD or come to the office for further evaluation,” Dr. Kroumpouzos said.

In his view, the brevity of the proposed screening tool makes it easy to incorporate into clinical practice, and the “yes or no” questions are practical. “It is crucial to elicit the presence of zoom dysmorphia in its early stage,” he said. “Zoom dysmorphia may trigger an increase in BDD, [so] it is essential to identify the presence of BDD in zoom dysmorphia sufferers and treat it appropriately.”

Dr. Kroumpouzos reported having no relevant financial disclosures.

Some hepatitis D virus (HDV)-infected patients may require longer treatment with bulevirtide than others, but even “nonresponders” according to US Food and Drug Administration (FDA) criteria may achieve reduced viremia with ALT normalization, based on real-world experience.

These findings suggest that longer follow-up is needed to determine the optimal treatment duration for bulevirtide monotherapy, reported lead author Alexander Killer, MD, of Heinrich Heine University Düsseldorf, Germany, and colleagues.

Heinrich Heine University

Bulevirtide was conditionally approved by the European Medicines Agency in 2020 and is on track for full marketing approval in Europe, but it remains unavailable in the United States, where Gilead, the manufacturer, has faced regulatory hurdles.

In the MYR202 and 301 clinical trials, bulevirtide significantly reduced HDV-RNA levels in 54% of patients after 24 weeks, and reduced viremia while normalizing ALT in 48% of patients after 48 weeks.

“Given its standalone status and good treatment tolerance even in patients with compensated cirrhosis, this represents a step change in the treatment of HDV-coinfected individuals,” Dr. Killer and colleagues wrote in Gastro Hep Advances.

Yet dynamics of response and clinical predictors of treatment outcome remain unclear, prompting Dr. Killer and colleagues to conduct the present retrospective study. The dataset included 15 patients who received bulevirtide for at least 1 year at a single center in Germany.

The analysis focused on monthly changes in biochemical and virologic parameters. The investigators also screened for clinical factors that might predict responses to therapy.

Treatment response rate and safety profile aligned with data from clinical trials, suggesting that bulevirtide is safe and effective in a real-world setting.

Patients typically achieved ALT normalization 2-6 months into therapy, followed by virologic response at least 6 months after starting treatment, with one-third of patients requiring at least 1 year to achieve HDV-RNA negativity.

“Of note, normalization of ALT under bulevirtide treatment occurs earlier than the decline of HDV-RNA levels, which contrasts with the response seen to nucleos(t)ide analog treatment in hepatitis B,” the investigators wrote. They suggested that this may be due to bulevirtide’s distinct mechanism of action.

Severe hepatitis was associated with lower response rates in the first year. Possible predictors of delayed response included low body mass index and high alpha-fetoprotein.

Of note, two patients had ALT normalization without virologic response.

“It is unclear whether these patients actually have worse outcomes in terms of overall success than patients with a combined response, especially since these patients experienced a decline of more than 1 log,” Dr. Killer and colleagues wrote, noting that a 1 log reduction is considered an intermediate virologic response, and hepatitis B virus (HBV) studies have shown that severe liver events are prevented by early ALT normalization. “Therefore, it does not seem appropriate to categorize patients with biochemical responses as ‘treatment nonresponders’ [according to FDA criteria].”

The investigators called for longer observational studies to determine the optimal duration of bulevirtide monotherapy.

This study was funded by the Ministry of Culture and Science of the State of North Rhine-Westphalia and the German Research Foundation. The investigators disclosed relationships with Novartis, GSK, AbbVie, and others.

SAN DIEGO — Fewer than half of the cancer drugs approved under the US Food and Drug Administration’s (FDA’s) accelerated approval pathway between 2013 and 2017 have been shown to improve overall survival or quality of life, despite being on the US market for more than 5 years, according to a new study. 

Under the program, drugs are approved for marketing if they show benefit in surrogate markers thought to indicate efficacy. Progression-free survival, tumor response, and duration of response are the most used surrogate markers for accelerated approvals of cancer drugs. These are based largely on imaging studies that show either a stop in growth in the case of progression-free survival or tumor shrinkage in the case of tumor response. 

Following accelerated approvals, companies are then supposed to show actual clinical benefit in confirmatory trials.

The problem with relying on surrogate markers for drug approvals is that they don’t always correlate with longer survival or improved quality of life, said Edward Cliff, MBBS, who presented the findings at the American Association for Cancer Research 2024 annual meeting (abstract 918). The study was also published in JAMA to coincide with the meeting presentation.

In some cancers, these markers work well, but in others they don’t, said Dr. Cliff, a hematology trainee at Brigham and Women’s Hospital, Boston, when the work was conducted, and now a hematology fellow at the Peter MacCallum Cancer Centre in Melbourne, Australia.

To determine whether cancer drugs granted accelerated approval ultimately show an overall survival or quality of life benefit, researchers reviewed 46 cancer drugs granted accelerated approvals between 2013 and 2017. Twenty (43%) were granted full approval after demonstrating survival or quality-of-life benefits. 

Nine, however, were converted to full approvals on the basis of surrogate markers. These include a full approval for pembrolizumab in previously treated recurrent or refractory head and neck squamous cell carcinoma and a full approval for nivolumab for refractory locally advanced or metastatic urothelial carcinoma, both based on tumor response rate and duration of response.

Of the remaining 17 drugs evaluated in the trial, 10 have been withdrawn and seven do not yet have confirmatory trial results. 

The reliance on surrogate markers means that these drugs are used for treatment, covered by insurance, and added to guidelines — all without solid evidence of real-world clinical benefit, said Dr. Cliff. 

However, the goal should not be to do away with the accelerated approval process, because it sometimes does deliver powerful agents to patients quickly. Instead, Dr. Cliff told this news organization, the system needs to be improved so that “we keep the speed while getting certainty around clinical benefits” with robust and timely confirmatory trials. 

In the meantime, “clinicians should communicate with patients about any residual uncertainty of clinical benefit when they offer novel therapies,” Dr. Cliff explained. “It’s important for them to have the information.”

There has been some progress on the issue. In December 2022, the US Congress passed the Food and Drug Administration Omnibus Reform Act. Among other things, the Act requires companies to have confirmation trials underway as a condition for accelerated approval, and to provide regular reports on their progress. The Act also expedites the withdrawal process for drugs that don’t show a benefit. 

The Act has been put to the test twice recently. In February, FDA used the expedited process to remove the multiple myeloma drug melphalan flufenamide from the market. Melphalan flufenamide hadn’t been sold in the US for quite some time, so the process wasn’t contentious. 

In March, Regeneron announced that accelerated approval for the follicular and diffuse B cell lymphoma drug odronextamab has been delayed pending enrollment in a confirmatory trial. 

“There have been some promising steps,” Dr. Cliff said, but much work needs to be done. 

Study moderator Shivaani Kummar, MD, agreed, noting that “the data is showing that the confirmatory trials aren’t happening at the pace which they should.” 

But the solution is not to curtail approvals; it’s to make sure that accelerated approval commitments are met, said Dr. Kummar.

Still, “as a practicing oncologist, I welcome the accelerated pathway,” Dr. Kummar, a medical oncologist/hematologist at Oregon Health & Science University, Portland, told this news organization. “I want the availability to my patients.” 

Having drugs approved on the basis of surrogate markers doesn’t necessarily mean patients are getting ineffective therapies, Dr. Kummar noted. For instance, if an agent just shrinks the tumor, it can sometimes still be “a huge clinical benefit because it can take the symptoms away.” 

As for prescribing drugs based on accelerated approvals, she said she tells her patients that trials have been promising, but we don’t know what the long-term effects are. She and her patient then make a decision together. 

The study was funded by Arnold Ventures. Dr. Kummar reported support from several companies, including Bayer, Gilead, and others. Dr. Cliff had no disclosures.

But the solution is not to curtail approvals; it’s to make sure that accelerated approval commitments are met, said Dr. Kummar.

Still, “as a practicing oncologist, I welcome the accelerated pathway,” Dr. Kummar, a medical oncologist/hematologist at Oregon Health & Science University, Portland, told this news organization. “I want the availability to my patients.” 

Having drugs approved on the basis of surrogate markers doesn’t necessarily mean patients are getting ineffective therapies, Dr. Kummar noted. For instance, if an agent just shrinks the tumor, it can sometimes still be “a huge clinical benefit because it can take the symptoms away.” 

As for prescribing drugs based on accelerated approvals, she said she tells her patients that trials have been promising, but we don’t know what the long-term effects are. She and her patient then make a decision together. 

The study was funded by Arnold Ventures. Dr. Kummar reported support from several companies, including Bayer, Gilead, and others. Dr. Cliff had no disclosures.

SAN DIEGO — Fewer than half of the cancer drugs approved under the US Food and Drug Administration’s (FDA’s) accelerated approval pathway between 2013 and 2017 have been shown to improve overall survival or quality of life, despite being on the US market for more than 5 years, according to a new study. 

Under the program, drugs are approved for marketing if they show benefit in surrogate markers thought to indicate efficacy. Progression-free survival, tumor response, and duration of response are the most used surrogate markers for accelerated approvals of cancer drugs. These are based largely on imaging studies that show either a stop in growth in the case of progression-free survival or tumor shrinkage in the case of tumor response. 

Following accelerated approvals, companies are then supposed to show actual clinical benefit in confirmatory trials.

The problem with relying on surrogate markers for drug approvals is that they don’t always correlate with longer survival or improved quality of life, said Edward Cliff, MBBS, who presented the findings at the American Association for Cancer Research 2024 annual meeting (abstract 918). The study was also published in JAMA to coincide with the meeting presentation.

In some cancers, these markers work well, but in others they don’t, said Dr. Cliff, a hematology trainee at Brigham and Women’s Hospital, Boston, when the work was conducted, and now a hematology fellow at the Peter MacCallum Cancer Centre in Melbourne, Australia.

To determine whether cancer drugs granted accelerated approval ultimately show an overall survival or quality of life benefit, researchers reviewed 46 cancer drugs granted accelerated approvals between 2013 and 2017. Twenty (43%) were granted full approval after demonstrating survival or quality-of-life benefits. 

Nine, however, were converted to full approvals on the basis of surrogate markers. These include a full approval for pembrolizumab in previously treated recurrent or refractory head and neck squamous cell carcinoma and a full approval for nivolumab for refractory locally advanced or metastatic urothelial carcinoma, both based on tumor response rate and duration of response.

Of the remaining 17 drugs evaluated in the trial, 10 have been withdrawn and seven do not yet have confirmatory trial results. 

The reliance on surrogate markers means that these drugs are used for treatment, covered by insurance, and added to guidelines — all without solid evidence of real-world clinical benefit, said Dr. Cliff. 

However, the goal should not be to do away with the accelerated approval process, because it sometimes does deliver powerful agents to patients quickly. Instead, Dr. Cliff told this news organization, the system needs to be improved so that “we keep the speed while getting certainty around clinical benefits” with robust and timely confirmatory trials. 

In the meantime, “clinicians should communicate with patients about any residual uncertainty of clinical benefit when they offer novel therapies,” Dr. Cliff explained. “It’s important for them to have the information.”

There has been some progress on the issue. In December 2022, the US Congress passed the Food and Drug Administration Omnibus Reform Act. Among other things, the Act requires companies to have confirmation trials underway as a condition for accelerated approval, and to provide regular reports on their progress. The Act also expedites the withdrawal process for drugs that don’t show a benefit. 

The Act has been put to the test twice recently. In February, FDA used the expedited process to remove the multiple myeloma drug melphalan flufenamide from the market. Melphalan flufenamide hadn’t been sold in the US for quite some time, so the process wasn’t contentious. 

In March, Regeneron announced that accelerated approval for the follicular and diffuse B cell lymphoma drug odronextamab has been delayed pending enrollment in a confirmatory trial. 

“There have been some promising steps,” Dr. Cliff said, but much work needs to be done. 

Study moderator Shivaani Kummar, MD, agreed, noting that “the data is showing that the confirmatory trials aren’t happening at the pace which they should.”
